PROCESS DESCRIPTION

Hydrogen sulfide, which forms in sewer networks, presents the sewer operators with serious problems. The reason for these problems is decomposition processes in waste water. In the absence of oxygen (O2), among other things, hydrogen sulphide forms, this is poisonous and has a strongly corrosive effect. Usual measures against hydrogen sulfide formation are injection of compressed air, compressed air rinses, adding chemicals and deodorising. These measures are often expensive or they only partially solve the problem.
